 Rough Carpentry  Framing, walls and roof  Finish Carpentry  Wood trim, shelving and handrails  Cabinetry  Cabinets and countertops

 Joists covered with OSB or Plywood Sheathing  Bearing on sills, walls or girders supported by posts

 P&G are used to support floor system  Posts are bid as counted items  Girders & beams bid as Linear Components

 Floor joists may be engineering I-Joists  Bid as counted item  If need joist blocking its counted as linear component

OSB = oriented strand board Engineered wood I-joist

 Treated as Sheet goods  Length of decking is assumed to run entire length of deck – when purchasing random lengths

 Consist of top and bottom plates, headers, hold downs (straps/ties), blocking, sheathing and obviously studs  Bidding  Top and Bottom Plates – Linear Components  Studs – linearly OR by quantity (depending on method)  May be in LF or Board Feet  Count the total of 2 x 4 lumber

A board foot, simply, is equal to 144 cubic inches of wood. Think of it as a piece I inch thick and 12 inches square. Since board footage is always calculated in quarters of an inch thickness, starting at no less than 1 inch (even if you order less than an inch, you’ll pay for the 1-inch thickness). In inches BF = Volume/144 = BF So a 2”x4”x8’ board = 2x4x96 = 768/144 = 5.3 BF 12 BF 1 BF
